金宗哲 최신의학사 1974 最新醫學 Vol.17 No.7

For the purpose of studying the effect of tetracycline on mineralization and growth, the rats were given a daily dose of 40mg. /kg. /day and 80mg. /kg. /day of tetracycline during the 8th-15th day of gestation. The effect of tetracycline on young rats delivered from adult rats receiving tetracycline had been assessed mainly through studies of body weight, length of tibia, size of mandible and contents of calcium. The latter was determined by atomic absorption spectrophotometry. The results were drawn as follows. 1. Tetracycline had the inhibitory effects on growth and mineralization in rats. 2. The more dosage of tetracycline had the severer inhibitory effects on growth and mineralization in rats. 3. The inhibitory effect on body weight was observed in group 1 (40mg. /kg. /day) during the 1st week after delivery, in group 2 (80mg. /kg. /day) during the 3rd week after delivery. The highest value of depression rate on body weight was 28.7% in group 2 (80mg. /kg. /day) at the 1st day after delivery. 4. The inhibitory effect on growth rate of tibia was observed in group 1 (40mg. /kg. /day) during the 2nd week after delivery, in group 2 (80mg. /kg. /day) during the 3rd week. after 4elivery. The highest value of depression rate on tibia growth was 36. 2% in group 2 (80mg. /kg. /&a.y) at the 1st day after delivery. 5. The inhibitory effect on growth rate of mandible was observed in group 1 (40mg. /kg. /day) during the 1st week after' delivery, in group 2 (80mg. /kg. /day) during the 3rd week after deiivery. 6. The calcium contents on mandible, tibia, anterior teeth and posterior teeth were incraasel in group 1 (40mg. /kg. /day) during the 1st week after delivery, in group 2 (80mg. /kg. /day) during the 4th week after delivery.

英國의 電子政府政策과 法制

金鍾鐵 법무부 2003 선진상사법률연구 Vol.- No.18

영국의 전자정부정책은 정보사회(information society)의 대두와 영국 헌정의 현대화(constitutional modernisation)라는 두 가지 배경하에 추진되고 있다. 전자정부는 시민과경제주체들의 정부서비스에의 접근과 활용을 원활하게 하기 위하여 정보통신기술을 활용하는 것을 의미하는데 정부서비스에의 정보통신기술의 적용은 정보사회로의 변화요구를 정부영역으로 수렴하는 것인 동시에 정부기능의 효율성을 제고하여 정부현대화를 촉진할 수 있기 때문이다. 이 글은 이 같은 배경을 가진 영국 전자정부정책의 추진현황과 이를 법적으로 뒷받침하는 제도의 변화에 대하여 소개하는 것을 목적으로 한다. 2000년 발표된 다국적 민간컨설팅 Deloitte Consulting의 공공영역연구보고서 "전자정부의 여명: 소비자로서의 시민"(At the Dawn of e-Government: The Citizen as customer)에 정리된 전자정부 진화 6단계 중 다기능 포털의 단계(multi-purpose portals)의 초입부에 있는 영국의 전자정부정책과 법제는 다음과 같은 세 가지 특성을 가지는 것으로 정리될 수 있겠다. 첫째, 전자정부정책은 여전히 17세기적 헌정구조를 기초하고 있는 지배체제를 현대화하려는 계획의 일부를 구성하고 있다. 둘째, 영국의 독특한 법체계적 특성에 따라 전자정부법제를 새로이 구축하는 방식이 아니라 기존의 법제에서 전자정부의 기반구축을 위하여 필요한 최소한의 부분을 보완하는 방식으로 마련하고 있다. 특히 전자정부와 전자상거래의 전제가 되는 전자서명을 비롯한 전자통신(electronic communications)의 법적 효력을 개별적 법영역들에서 추가적으로 인정하는 방식을 취하는 한편 전자정부구축의 전제가 되는 정보공개와 개인정보보호도 특별한 개별입법이나 조치없이 일반법원칙에 따라 처리하고 있음을 확인할 수 있다. 셋째, 전자정부화는 지구촌화(globalization)라는 시대적 조류에 따라 탈국가적 무한경쟁이 일상화된 상황에서 전자상거래의 획기적 발전을 제도적으로 뒷받침하는 기능을 수행하고 있다. 넷째, 전자정부정책의 지속적 발전을 도모하면서도 그에 따른 변화가 요구하는 정부의 민주적 책임성의 강화나 국민의 기본권침해의 예방을 위해 통일적인 법제의 정비가 요청된다. E-government policy in the UK can be best understood in two backgrounds: the one is the advent of information society in general and the other is constitutional modernisation movement in the UK. These backgrounds come across at the crossroad of e-government. The advent of information age requires the transformation of delivery of government services, which in turn offers an opportunity for restructuring the out-of-date British governmental system. In this essay, providing a chronological sketch of Blair Government's e-government policy and its accompanying legislation, the author points out four features of the UK e-government policy and legislation. First, e-government policy is part and parcel of modernising government project, a primary agendum of Blair's reform drive. Second, there is no new primary legislation planned for e-government but a number of statutory instruments authorized by the Electronic Communications Act 2000 enacted to recognize legal effect of electronic communications play important role in facilitating not only e-government but also e-commerce. The Freedom of Information Act 2000 and the Data Protection Act 1998 provides indirect legal basis for e-government too. Third, e-government goes hand in hand with e-commerce as the latter is regarded as the basis for the advance of the former and vice versa. Fourth, since e-government policy may change not only the relationship between government and citizen but also the way that government itself is structured and organised, there is a need for a comprehensive primary legal framework to ensure government's accountability as well as protect citizen's human rights in information age.

Measuring the thermophysical properties of solids in laser heating method, the material surface is coated by thin black paint layer(graphite) to minimize the effects of the laser beam reflection. But, the influence of the thin black paint layer on the surface temperature variations have been ignored. In this paper, a numerical analysis is carried out to clarify quantitatively the influence of the thin black paint layer when the material surface is heated locally. In the experiment, the material surface is heated by Ar laser beam and the surface temperature profiles are measured by an infrared thermometer.

金鐘喆 충주대학교 1994 한국교통대학교 논문집 Vol.29 No.1

Factors that affect cutting temperatures are studied in this paper. Experiments have been made by varing the cutting speed, the depth of cut, and the feed speed. As a result it is showed that rising temperature was the highest in cutting speed change, and it was the lowest in feed speed change. In cutting speed versus tool wear the width of tool wear was more wide in Flank Wear than in Cratering Wear as cutting speed was faster.

In this paper, grinding condition, I have studied on the surface roughness and cutting force. I have obtained the results as follows : 1. In relation to surface roughness vs, grain sige, the grain sige number increased in sign. The more depth of cut was short the better surface roughness has appeared. In relation to feed speed vs. depth of cut, the more feed speed and depth of cut increased the more surface roughness has badly appeared. 2. In the grinding gorce, I have obtained the conclusion when vertical component of cutting force and axial component of cutting force were changed grinding condition. P?=C₁d???? P?=C₂d????

식물응집소 Vicia pallida Turcz. 및 개 적혈구에 의한 사람 혈청형에 관한 연구

Some plant extracts are known to have biological activities as phytagglutinins (PHA's) and, in recent medicolegal studies, human sera were classified by their agglutination inhibiting properties to animal red blood cells. Vicia pallida Turcz. acts as pan-PHA to dog red blood cells. Therefore the author carried out agglutination inhibition test on Vicia pallida extract to dog red blood cells with 851 human sera, and the results are compared with known blood and serum types. The results are obtained as follows: 1. Human sera could be classified into two groups. One group inhibited agglutinating activities of vicia pallida extracts to dog red blood cells and the other did not. 2. The distribution of the former was 15% and the latter was 85%. 3. The agglutination inhibiting phenomena of human sera on Vicia pallida extract to dog red blood cells showed no constant relation with known blood and serum types such as ABO, MN, H, CI, Htr, PVI and CCI respectively. 4. This new classification of human sera is considered to be applicable to individual identification of blood stains.

旋削에서의 切削抵抗에 關한 硏究

金鐘喆 忠州大學校 1981 한국교통대학교 논문집 Vol.14 No.2

The effect of tool wear, B.U.E.. and chattering which occurs in the process of cutting varies with the cutting condition. This article aims to search the cutting force in theoretical by studying the degree of cutting force when we change the depth of cut, feed, bite angle and cutting speed with oblique dimension of cutting force. In the result of the teat the more depth of cut increases, the more cutting force is increased, and more feed is in order, But it turned out that the more back rake angle increases, the less cutting force is.
